Perfect Binary Tree

Famous quotes containing the words perfect and/or tree:

    How soon unaccountable I became tired and sick,
    Till rising and gliding out, I wander’d off by myself,
    In the mystical moist night-air, and from time to time,
    Look’d up in perfect silence at the stars.
    Walt Whitman (1819–1892)

    A tree there is that from its topmost bough
    Is half all glittering flame and half all green
    Abounding foliage moistened with the dew;
    And half is half and yet is all the scene;
    And half and half consume what they renew....
    William Butler Yeats (1865–1939)
